1. A trip actuator for a switch of an electric power circuit, the trip actuator comprising:
a main driving unit including an output unit which is linearly movable; and a sub driving unit including a portion connected to the output unit, and a a drive unit to drive the portion, the sub driving unit operating to linearly move the output unit, before the main driving unit operates, upon opening the electric power circuit. |
